Wow. Seven new development projects. Not one of them a Lunar lander. :-(

Or the ability to refuel one, no?  Or is that the "utilization module?"

Cislunar Space Habitation Ė Paving the Way to Mars

Orbital ATK
Published on May 9, 2018

Orbital ATKís vision for the next step toward human space missions to Mars employs our flight-proven Cygnus advanced maneuvering spacecraft as a human habitat in cislunar space, the region between the Moon and Earth. In the early 2020s, we would launch the initial habitat on NASAís SLS rocket. Featuring a modular design, the habitat would serve both as a destination for crewed missions and as an unmanned testbed to prove-out the technologies needed for long-duration human space missions. The habitat is also envisioned as a base for lunar missions by international partners or commercial ventures. With additional habitation and propulsion modules, the habitat could be outfitted for a Mars pathfinder mission.

New LOP-G article:

The Lunar Orbital Platform-Gateway: an unneeded and costly diversion
Quote
Two components have emerged in NASAís plans to return to the Moon. The first is to establish a human tended space station in lunar orbit. Originally called the Deep Space Gateway, this program was renamed the Lunar Orbital Platform-Gateway (LOP-G) by the Trump Administration. The second component is to return humans to the surface of the Moon and establish a lunar base. Thus far NASA has been short on details regarding the latter.

But can we afford to do both components? The answer is a resounding no! Returning humans to the lunar surface is the primary goal of the Trump Administration and is the consensus goal. It is a goal that will inspire the public and the next generation of scientists and engineers. LOP-G is an unneeded and costly diversion that should be promptly relegated to the dustbin of history.

One point made in the above article could have been expanded upon:
Quote
In lunar orbit, the crew would be subjected to the deleterious effects of radiation (double that of LEO) and microgravity. These conditions would require frequent crew rotation. But if crews went directly to the lunar surface, they could stay for lengthy periods of time. They would be protected from radiation by a habitat covered by lunar dirt, and lunar gravity (16 percent of Earth’s gravity) is bound to be less harmful on the bones and muscles than micro-gravity.

But how much less harmful?

Lunar gravity is much closer to Martian gravity (0.38G) than either zero-G (LOP-G) or Earth at one G.  It would be very useful to add that data point to our low gravity human tolerance testing.  Three points (0G, 0.16G, and 1G) would be much more informative relative to Mars 0.38G than just the two bookends.
